Acylindrical specimen of aluminum having a diameter of 19 mm and length of 200 mm is deformed elastically in tension with a force of 48,800 n. using the data contained in table 6.1 determine the following: (a) the amount by which this specimen will elongate in the direction of the applied stress, (b) the change in diameter of the specimen. will the diameter increase or decrease? data for aluminum from table 6.1: modulus of elasticity 69 gpa or 10 106psishear modulus 25 gpa or 3.6 106psipoisson ratio 0.33

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called
